AR15 9MM MAG WELL ADAPTOR FOR COLT / UZI STYLE

This is a great adapter for your colt style 9mm mags. First off I'll start with the very minor negatives. 1. It didn't come with any instructions, but it's easy enough to figure out. [[Unscrew the little screw w/ washer on the top, slide the adapter up in from the bottom, replace the screw n washer when the top of the adapter is flush this will ensure that it doesn't drop out, then set the two set screws on the bottom]] 2. It was a little bowed out on the sides, so I had to bend the thin metal in gently just a little with some channel locks. Now the positives. 1. Broke in my new PSA 9mm pistol w/ CQB PDW brace with 200 rds and had 1 double feed using 32 rd ASC mags. It's the mags fault, but I'm putting it here anyway. 2. The hold open feature worked flawlessly for me with the standard bolt & buffer. 3. The ASC mags were a tight fit at first, needed to give them a bump to get them to seat. But now with 500 rounds through it, it's loosened up a little and seats solidly without the bump. 4. Mag release has worked flawlessly from the get-go. 5. 2 32-rd rapid fire mag dumps with the new TPJ ammo at the end of my last session went without issue. 6. After cleaning my 9mm pistol, the adapter hadn't noticeably moved at all. Awesome adapter. Get it.

Works very well with my Colt 9mm upper. It is a snug fit in my lower, so snug that I didn't need the set screws to hold the adapter in place.

I chose the KAK mag adapter after comparing it to some of the other ones out there. The ProMag version didn't have a bolt hold open feature and was mainly made of plastic, and the Hann adapter was a little bit beyond my budget. This Kak adapter had all of the features I was looking for. It installs from the bottom (which means I don't have to remove the bolt catch on my AR if I ever need to convert it back to 5.56mm), has set screws that hold it snuggly in place inside the mag well, has good built in feed ramps, works with the normal AR magazine release button to pop out the empty mags, and has the bolt hold open feature on the last round. The KAK was THE ONLY 9mm mag adapter that has all of those features at $100. Everything fit nicely on my AR and there was no slop in the mag well. The adapter itself is made of some pretty hefty sheet metal. I am looking forward to many years of use on this adapter.

Really wanted an AR-9 but wanted the ability to use existing registered SBR lower. I did a ton of research and have used other KAK products so this was a clear choice. It fits great in both lowers and functions properly. I've run about 10 mags through and competed in 1 PCC match so far with no issues, that weren't operator related, using standard and suppressed Subs. There are set screws to tighten the fit but mine fits perfect with no wiggle. The swap from one lower to another is easy enough and it is positively locked in place while in use. Remove the small allen screw and drop it out like an mag. The only thing that would make this better would be a tool-less integrated lock. I'm gonna lose the screw or washer at the range one of these days. Overall it was exactly what I needed for my desired build.

Have not completed build yet. Had to remove bolt catch because no instructions on order to install parts. Seems like a good product.S&H a little high,snail mail shipping. Roll pin dinged cerakote job when removing bolt catch, which was unnecessary if you didn't have to read between the lines. Everyone is not an experienced builder. Half the price of Hahn

dropped right into magwell, retaining screw was simple to install, locks in just fine with no wiggle, mags release no problem I ended up polishing the feed ramp with cratex but not really needed, just out of habit ran great - i would have no concern ordering another in the future if I needed one

I received the mag well adapter very quickly from KAK. It went into my registered SBR lower very snug but without too much difficulty. I love the top screw that that keeps it from coming out when the mag release is depressed. The way they made it to operate the standard bolt catch is great since I use this lower for other calibers as well. I had difficulty adjusting the two little set screws on the lower front of the adapter, but the fit in my mag well is so good these set screws are unnecessary. On my first trip to the range I was plagued with numerous failures to eject. With both my hand loaded rounds and a box of Winchester 124gr NATO ammo. I did some research on line and decided to try putting a little bend in the ejector. I bent it in toward the bolt a little and slightly down. Next trip to the range I fired over 100 rounds with no malfunctions of any kind. This was with factory round nose ammo and my light (USPSA) flat nose loads. Locked back every time after the last round on all 4 of my ASC 32 round mags, and my friend's metalform mag. I also bought the 8oz extended carbine buffer to go with this build on my 10.5" PSA upper. Very pleased with reliability and accuracy of this combo. USPSA PCC division here I come.

This adaptor works very well

I'm very happy with the quality of this adapter. KAK has done very well with this product at a very reasonable price. 2 thumbs up.
